The development of sex organs in female alfalfa weevils (Hypera postica (Gyllential)) during aestivation was studied. Females were dissected at monthly intervals to study the progressive stages of sexual maturation. Weevils that emerged from cocoons in way entered into an apparent diapause stage until October. Morphological growth of the female sex organs was considerably arrested during diapause, and sexual maturity was not reached until November 23. Adults which emerged in September did not diapause and the females also attained sexual maturity on November 23. Diapausing weevils required 6 months to mature whereas nondiapausing weevils reached maturity 81 days after emerging from cocoons.
